High temperature resistance of artificial marble, or natural marble high temperature?
Because of the natural stone surface pores, so in the area of pollution is relatively poor, generally in the processing plant will be in its surface treatment. In the interior decoration, the TV table, windowsill, indoor floor, such as the use of marble. The threshold, cabinets countertops, outdoor ground is suitable for the use of granite. Which is a good view of the cabinet is the use of dark granite.Now on sale in the market of natural stone, part of the color is artificially processed, these stones generally use six months to a year will reveal its true face. It is clear that the market is now a big flower green, many are dyed, not really the original color.Also pay attention to the back of the grid, there are two: first, the stone itself is brittle, must add the grid, such as Spain beige. Cut corners, the thickness of these stones is thin, the intensity is not enough, so the network. The general color of the stone if there is a style, most of which is the reason.
Marble is a metamorphic rock formed by high temperature and high pressure in the earth's crust. The internal force of the earth's crust promotes the change of the original rocks, that is, the structure, structure and mineral composition of the original rock. After the formation of a new rock metamorphic rock.Marble is mainly composed of calcite, limestone, serpentine and dolomite. The main components of calcium carbonate, accounting for more than 50%. As a result of the marble generally contain impurities, and calcium carbonate in the atmosphere by carbon dioxide, carbide, water vapor, but also easy to weathering and corrosion, and make the surface soon lose luster. The general nature of the marble is relatively soft, which is relative to granite.
Natural stone is mainly divided into two kinds: marble and granite. Generally, there is a texture, known as "marble"; to spot the main point, known as "granite". This is broadly speaking. In a narrow sense, marble refers to the stone produced in Yunnan, Dali. In fact, there are not many stones around the country is out of Dali.They can also be distinguished from geological concepts. Granite is igneous rock, also called acid crystallization plutonic rocks, is one of the most widely distributed rock in igneous rock composed of feldspar, quartz and mica, hard rock compacting. The composition of silica based, accounting for about 65%-75%.The igneous rock is lava condensation crystallization of magma or volcano eruption and rock. The content of silica, the properties and content of feldspar determine the properties of stone. When the content of silica is greater than 65%, it belongs to the acid rock, the rock in the feldspar, Xie Changshi, quartz and other basic minerals to form crystals, a material like structure, known as granite.
